Thanks!
How do you offer the food? I'm guessing some kind of feeding dish would be best. Again, is there a way of insuring the veggies are safe? I'm not so much concerned for the roaches(haha!) as I am for the animals that will be eating them. Am I the only one here who thinks these roaches look disgusting btw? Other roaches I can take, but these kinds...erp. Ok, the nymphs are kind of cute...but it is more of a "Ok squirmy critter let me throw you in with my real pets so you can dissapear as quickly as possible!"
It seems a sponge would require changing often and get smelly, no? Maybe a waterdish filled with pea gravel would work? Only problem is that the nymphs would no be able to get to it...and if they could they'd drown of course. Another idea could be providing a smaller container with some kind of substrate that could be made wet every once in a while. Maybe even a plant to keep it fresh?
Also, is their any kind of plastic that they would appreciate for shelter? Something that can be removed and sanitized easily?
